iam read perfect. I only say where write the english is medium. Now stop of criticize needlessly about of reading, your language not is higher compared with other languages. do not be arrogant.
===========================
Ok, get the minecraft_server.jar, and download minecraftforge for discard the minecraft_server? Only can install and use the minecraft-universal for use the Minecraft+MOD, but and the Plugins??? Not encounter this Jar File. Only seek the CraftBukkit (Minecraft+Plugins) but not have MODs. 
i understand what this problem not have suported in this forum, but not have other place what this for resolver this problem, because you have the using the IC2 with Server and Client, and know how to install the complete Minecraft+MOD+Plugins.
Actually, you are the one being arrogant, because we can't understand you properly what you are saying nor what you want. You do not speak, read nor anything related to english.
That said, the fact you dont speak english is what causes all this problem.
If you have read what we said properly you would have understood that you can not easily create modded servers with plugins and should use a normal server without plugins.
That way, CraftBukkit, Bukkit, MCPC+ ... are crap.
To create a Modded Minecraft with server plugins you need help from other people, (the ones that work with the server plugins, MCPC+/bukkit forum, not IC² forum)
We only provide proper support to Modded Minecraft on normal servers (NO PLUGINS). Therefore this thread and the other two are pointless.
Thread Closed, do NOT open a new one if you are still asking for help to create a server WITH plugins, you have been warned.
